Application filed October ll, 1890. Serial No. 367,861. (No model.)

To all whom 'it may concern: rugated sections being to draw the board on- Be it known that I, LUTHER E. PAINE, of ward and that of the disks to travel in the Edinburg, county of Johnson, and State of kerfs formed by the saws and prevent their 55 Indiana, have invented cert-ain new and usecoming together and cramping the saws in ful Improvements in Self-Feed Rip-Sawing their work.

Y 55 description. 33 are set-screws working in slots formed In the drawings, Figure l is a side elevain the enlarged ends of cross-bars 34 of which tion. Fig. 2 is a top plan view. Fig. 3 is a two are provided at each end of the lower detail perspective view of the frame that carframe-work 25, and by loosening these setries the boxings for the shafts of the feedscrews the axles of the feed-rolls, with their 7o 1-0115, boxings, may be bodily removed and set un 2o ln detail, l is the frame-work of the mader the inner cross-bars when itis desired to chine, providing bearings for the main shaft feed closer to the saws, and vice versa. Of 2, on which is mounted the driving-pulley 3, course in doing this some links will have to driven by a belt 4t, leading to the line shaft or be removed from the sprocket-chains which 75 engine. Upon the main shaft, about midway drive the feed-rolls. Again, if the board is beneath the top, is mounted a second pulley, disposed to leave the fence-board 53, then by (not shown,) from which a belt 5 leads to a loosening the set-screws 33 the forward feeddriving-pulley 6, mounted on a countershaft roll may be moved slightly toward the saw, 7, havinga small pulley S on the outer end, and this will feed the lumber toward the 8o from which a belt 9 leads to a pulley 10, fence-board, and if, the board binds against mounted on a counter-shaft 1l, having a centhe fence-board too much by the same means tral bearing in abrack et l2, bolted to the top the feed-roll may be set farther back. A of the table. similar adjustment, of course, is possible with 14 is a movable frame-woilk carried on the the rear feed-roll whenever the same may be- 8 5 counter-shaft 1l, with which is connected an` come necessary. operating-lever l5. is a rod pivoted at 3G to a stationary 16 is a counter-shaft journaled in boxings arm 37, extending upward from the bracket 17, formed integral with the frame le, and on l2, and this rod is pivoted at 38 to an arm 39, the outer end ot' this shaft is mounted alarge formed on and connected with the lower 9o sprocket-wheel 18, from which a drive-chain frame 25. rIhrough this rod the two frames 4o 19 leads to a smaller sprocket 20, mounted on 14 and 25 are connected, so as to be operated the counter-shaft ll inside of the pulley lO. simultaneously by the movement of the lever 2l and 22 are similar sprocket-wheels, which 15. The connection thus made through this are also mounted on the counter-shaft 1G. A arm between the upper and lower frames se- 9 5 drive-chain leads from the sprocket 2l to a cures a simultaneous vertical movement of sprocket 23, mounted on a shaft 24E, which is the axles of the front and rear feed-rolls, carried in boxings 29, connected to the lower keeping them always in the same horizontal frame 25, hung upon the axle 16 outside and plane with each other, so that when one is below the frame 14. The shaft 24 carries lifted by the movement of the lever the other Ico upon its opposite end, directly over the table is correspondingly lifted, and when the board 5o in line with and behind the saws, a feedhas passed out from beneath the front feedwheel 26, composed of corrugated sections, roll such roll will not drop down, but will with disks 27 interposed, the office of the cor continue in the same position while the board is passing beneath the roll on the opposite side, and this allows a new board to be inserted and fed beneath thev front feed-roll, while the board that has just passed is still under the control of the 'feed-roll behind the saws.

40 is a lever pivoted at 4l to the machineframe below, on which is mounted a counter-weight 42, which is adjustable on the end of such lever, so as to increase or decrease the pressure of the feed-rolls.

At 43 is a rod, which connects the upper lever 15 to the lower lever 40, enabling the adjustable weight 42 upon the end of the lever 40 to control the pressure of the feed-rolls upon the boards.

44 is a clutch formed on the hub 45 of the sprocket-wheel 20, this clutch being adapted to engage with a similar part formed on the hub of the pulley 10. This clutch may be thrown in or out of gear with its corresponding part by means of a rod 46, whose-inner forked end 47 works in a groove formed in the hub 45 of the sprocket-wheel 20, so that by turning this rod, which is provided with a bend or handle 49, over to the left the clutch 44 is disengaged, and it, with its sprocket-wheel, is thrown to the left on the shaft 11, so that the sprocket is no longer operated by the revolution of the pulley 10, and the feed mechanism will then cease to revolve, while the saws continue to work.

50 is a strap bolted to the side of the machine-frame, having holes to receive a pin, so that when it is desired to throw the feed mechanism up out of the way it may be locked by means of the pin in any one of the holes of the strap. This lever is also used for the purpose of adjusting the feed-rolls to any t-hickness of stulf desired.

The corrugated sections of the feed-rolls and the disks, which have knife or beveled edges, are all detachable, and may be removed from the shafts on which they are carried after unscrewing the nuts, and it will be easy to increase or decrease the number of these sections, so as to correspondingly vary the length of the rolls, if desired. friction-rolls 5l are mounted beneath the table, so that the board passes between these and the upper feed-rolls.

The counter-shaft 1G is journaled not only in the boXings 17, formed upon the upper frame 14, but also in boxings 52. connected with the lower frame 25, so that the two frames are united at this central point by this shaft as well as by the connecting-106135, and thus are operated simultaneously by either the upper lever 15 or the lower lever 40, and the counter-weight 42 of the latter is thus enabled to control the pressure of the feed-rolls upon the material.

What I claim as my invention, and desire to secure by Letters Patent, is the following:

l. In a rip-sawingmachine, a main frame, a

driving-shaft 'ournaled therein carr infr a pulley on one end and saws on the other, a

The usualI bracket bolted to such frame or table, an upper.vertically-swinging frame journaled on a shaft carried in bearings connected tc such bracket, a lower frame connected beneath to such swinging frame, a counter-shaft journaled therein, front and rear feed-rolls detachably mounted on such shafts, such upper and lower frames connected by a shaft passing centrally through both, sprocket-Wheels mounted on such shaft, drive-chains leading therefrom to sprocket-wheels carried on the shafts of the feed-rolls, and a lever connected to such upper vertically-swinging frame for operating the same, whereby the upper and lower frames may be lifted simultaneously and the front and rear feed-rolls maintained in the same horizontal plane, all combined substantially as shown and described.

2. In a rip-sawing machine, a frame, a main shaft journaled therein, a driving-pulley and saws mounted on such shaft, front and rear feed-rolls mounted on counter-shafts journaled in boxings adjustably connected to an auxiliary frame, sprocket mechanism connected to the other end of the feed-roll, shafts for driving the same, a vertical frame swinging on a counter-shaft mounted in bearings on a bracket connected to the main frame or table, such swinging frame connected to the auxiliary frame below by a shaft centrally j ournaled in both and carrying sprocketwheels for driving the feed-rolls, an auxiliary pulley mounted upon a shaft having bearings above the machine-table driven by belts from the main shaft, a clutch mechanism located inside such pulley, and a rod connected thereto for operating the same so as to throw the feed-rolls 1n or out of gear, as desired, and a lever pivoted to the main frame above, having an adjustable weight on its` inner end for regulating the pressure of the feed-rolls upon the material, all combined substantially as shown and described.

3. In a rip-sawing machine, a frame, adriving-shaft carrying a pulley and saws mounted in bearings thereon, feed-rolls mounted on shafts carried in, a vertically-movable frame,

sprocket-wheels mounted on the shafts of the feed-rolls and on a central counter-shaft for driving the` feed-rolls, drive-chains leading from such sprocket-wheels to a counter-shaft driven by belts from the main shaft, a lever for lifting the verticallymovable frame,

whereby the relative position of the feed-rolls is maintained in the same horizontal plane, such lever connected to alever pivoted to the machine-frame below, and a 'counter-weight mounted on such lower lever and adjustable thereon for regulating the pressure of the feed-rolls upon the material, all combined substantially as shown and described.

In witness whereof I have hereunto set my hand this 4th day of October, 1890.
